Application filed January 12,- 1924; Seraf Nol '685,875'

lducin-g articles having a shell like formation such as trays, baskets', vases, boxes, hand bags, andI similar objects wherein' the form only of the shell Walls gives the article its particular characteristic,- andthe nature of thel Walls give the article. its strength.

rlhe objects of my inventionare to provid-e means by which' sucl-i articles of tlxiinA wal-l or shell structure may be readily formed to any desired sha-pe .either of a' mechanical or ornamental nature", butprincipa'lly the latter so as to meet tl-iedemafnd for a great variety of formsl for anyor allof the articles above mentioned or otherswhich may be adaptedl to my process. v

An example of a form produced according fio-my invention is shownin Figure of .the drawings accoiiipafnyiiig this syiiecica'tion, the representation being' that of a fancy fruit basket shown in perspective. Figure 2 isA al similar vi'ewvyo'f the frame structure Within the Walls of the basket and Which consists of a niece of Wire cloth or netting' shaped to the form of the article which it is desired to produce,'-in this example, the fruit basket.

Figures 3 and et are perspective vieivs of a box and lid made in accordance with my invention, and Figure 5 is an enlarged sectional' vieiv of a piece of the Wire inner structure of my shell Wall con struction slioiv ing the paper glued to both sides and the niiisn coating applied to the outside of the Figure l, it may have other pieces of netting or separate Wires (2) attached to it to form any auxiliary members on the article, such for instance as the handle (3) ni which the Wirl) is concealed'. The lWire netting is then covered on both sideswith a sheet of'pan'er, or cloth, but preferably soft paper secured by glue orother adhesive; rElie `paper is lforced tightly into the meshes of the Wire cloth so as to adhere firmly to all the Wires as Well as to the paper on; the other side. After theI paper or cloth is pasted to4 the vvire as described, it then receives a finishing coat either of silk or'other decorative cloth glued to it, or, is coinpletely enveloped in a-Vcenientitious plaster to form the shell Wallsofthearticle and further hold the Wire netting in the shape to 'which it .has beenfornied.

There'are many plastic compounds available Which are suitable for forming" the Walls, but l prefer the putty like coiiiljounds used `for modeling ornamental devices, and which may be Worked into the meslies offtli'e netting' from both sides', ands'i'f desired given' a distinctive surface texturel as indicated at in Figures l and 3, alsofo'rined into any other desirableV` orn'ai'iieiitat'ion suc'li as the fruit and leaves vshown atY v at the juncture of' the handle (3l and the sides of the basket inl Figure 1.

j if cemen'ti'tious composition 'be used it` shou'ld" be of a Kcharacter-v which plastic vvhile' being-applied and which" harde'n'sinto a stone like material, thus rendering perinanent the shape given the wire netting.

In Figure 5 the construction above explained will be readily understood, (l) is the wire cloth, (7) is the paper glued in place, and (8) is either the composition cenientitious coating or the finishing cloth pasted to the paper.

As the object of' gluing soft paper to the Wire is to till or bridge the holes lbetween the Wires it is obvious that paper on one side only could be used though it would not be so strong, or the Wire could be dipped in heavy glue to bridge or partially bridge the gaps With a film of glue, before vapplying the composition coating', or the composition could be applied to the Wire Without the paper first being applied to the Wire, but the invention is best carried out by the complete construction described.

When the composition coating is used outside of the paper it is allowed to thoroughly harden and is then given one oi" more coats of paint or varnish to Waterlou proof it and prevent softening of the composition 1n ease hot water 1s used 1n the .finished article.

When making articles such as the boX shown in Figure 3, the corners of the wire frame, also the juncture of the bottom to the sides need not be soldered, if made of separate pieces of wire netting, for if lightly stitched with stout thread or light wire will be amply strong, as the paper when glued to both sides of the wire in the manner described will thoroughly reinforce the joints and when the composition is applied the article virtually becomes a unitary structure.

In contemplating the wire structure of my invention it will be seen to differ from the mere reinforcing` of a cement article, for in the latter case the reinforcement does not represent the finished form of the article, nor is it co-extensive with the walls of the article as it does not extend to every remote part but is subservient to the form, whereas with my method the reinforcement actually is the finished form, the paper and other external coatings serving to permanently sustain the form and make it presentable to the eye.

l claim:

1. The method of producing three dimensional shell forms which consists in shaping a foraminous material to the finished form co-extensive therewith and of then securing it in such a condition by the application thereto of a plastic cementitious material .for subsequent hardening.

2. rllhe method of producing three dimensional shell forrns which consists in shaping. wire cloth to the finished form and of then securing it in such a pre-shaped condition by the application of a cementitious coating;

to both sides of the wire cloth to formV a wall having sides substantially parallel to the two sides of the wire cloth.

3. The method of producing a three di mensional shell like form which consists.

4. The method of producing forms in y three dimensions which consists in shaping a wire cloth to the finished form and coezitensive therewith, gluing; a fibrous sheet of material to the wire cloth and applying a finishing coat to the outer surface of the fibrous sheet.

5. The method of producing three dimensional shell forms which consist in shaping wire cloth to the finished form, gluing paper to the side of the wire cloth and then covering both sides with a cementitious coating.

6. The method of producing three dimensional'shell forms which consists in shaping wire cloth to the iinished form and coextensive therewith, gluing paper to both sides of the wire cloth and then covering both sides with a cementious coating and painting the ceinentitious coating.

7. The method of producing a fruit basket or the like which consists in bending a sheet of wire cloth to the shape of the bas het with upwardly extending walls, of con necting opposite walls with a. wire loop, and of applying` plastic cement to both sides of the wire cloth and the wire loop and alloiy1 ing the cement to harden.
